1);combobox1.InsertText(0, Item - 2);combobox1.InsertText(0, Item - 3);combobox1.InsertText(0, Item - 4);combobox1.InsertText(0, Item - 5);combobox1.InsertText(0, Item - 6);combobox1.InsertText(0, Item - 7);combobox1.InsertText(0, Item - 8);combobox1.Active 5;} ComboBoxEntry框 ComboBoxEntry框是可输入的用法同ComboBox。 TreeView列表 这框比较有特色可显示图片和文本。图片用Gdk.Pixbuf装载是个特殊类型。 protected void OnButton15Clicked(object sender, EventArgs e){Gtk.ListStore listStore new Gtk.ListStore(typeof(Gdk.Pixbuf), typeof(string), typeof(string));treeview1.Model null;treeview1.AppendColumn(Icon, new Gtk.CellRendererPixbuf(), pixbuf, 0);treeview1.AppendColumn(Artist, new Gtk.CellRendererText(), text, 1);treeview1.AppendColumn(Title, new Gtk.CellRendererText(), text, 2);listStore.AppendValues(new Gdk.Pixbuf(sample.png), Rupert, Yellow bananas);treeview1.Model listStore;listStore.Dispose();} DrawArea Cairo 图像 是做图用的先创建surface,可以在内存中、图片上、pdf上、DrawArea上画图或写字也可以存成png图片图形可以变换座标。在内存中绘图然后在DrawAre的context上show显示或在其它地方显示。功能很灵活与GDI在bitmap上做图通过hdc显示在pictureBox上有对比性。 protected void OnButton11Clicked(object sender, EventArgs e){//// Creates an Image-based surface with with data stored in// ARGB32 format. //drawingarea1Width drawingarea1.Allocation.Width;drawingarea1Height drawingarea1.Allocation.Height;ImageSurface surface new ImageSurface(Format.ARGB32, drawingarea1Width, drawingarea1Height);// Create a context, using is used here to ensure that the// context is Disposed once we are done////using (Context ctx new Cairo.Context(surface))using (Context ctx Gdk.CairoHelper.Create(drawingarea1.GdkWindow)){// Select a font to draw withctx.SelectFontFace(serif, FontSlant.Normal, FontWeight.Bold);ctx.SetFontSize(32.0);// Select a color (blue)ctx.SetSourceRGB(0, 0, 1);//ctx.LineTo(new PointD(iArea1ObjX, drawingarea1.Allocation.Height));//ctx.StrokePreserve();// Drawctx.MoveTo(iArea1ObjX, iArea1ObjY);ctx.ShowText(Hello, World);/*//Drawings can be save to png picture file//surface.WriteToPng(test.png);//Context ctxArea1 Gdk.CairoHelper.Create(drawingarea1.GdkWindow);//Surface surface1 new Cairo.ImageSurface(test.png);//Option: coordinator change, origin 0,0 is the middle of the drawingarea//ctxArea1.Translate(drawingarea1Width / 2, drawingarea1Height / 2);//surface.Show(ctxArea1, 0, 0);//ctxArea1.Dispose();*/}} About对话框 固定格式的对话框有贡献者、文档人员、版权说明等与windows的about不太相同。 protected void OnButton9Clicked(object sender, EventArgs e){string[] textabout {abcde,fdadf,adsfasdf };const string LicensePath COPYING.txt;Gtk.AboutDialog aboutDialog new Gtk.AboutDialog();aboutDialog.Title About mono learning;aboutDialog.Documenters textabout;//aboutDialog.License mit license;aboutDialog.ProgramName my Program;aboutDialog.Logo new Gdk.Pixbuf(logo.png);//aboutDialog.LogoIconName logo.png;//aboutDialog.AddButton(New-Button, 1);aboutDialog.Artists textabout;aboutDialog.Authors textabout;aboutDialog.Comments This is the comments;aboutDialog.Copyright The copyright;aboutDialog.TranslatorCredits translators;aboutDialog.Version 1.12;aboutDialog.WrapLicense true;aboutDialog.Website www.me.com;aboutDialog.WebsiteLabel A website;aboutDialog.WindowPosition WindowPosition.Mouse;try{aboutDialog.License System.IO.File.ReadAllText(LicensePath);}catch (System.IO.FileNotFoundException){aboutDialog.License Could not load license file LicensePath .\nGo to http://www.abcd.org;}aboutDialog.Run();aboutDialog.Destroy();aboutDialog.Dispose();} Timer时钟 使用Glib的时钟100ms timerID1  GLib.Timeout.Add(100, OnTimedEvent1); 使用System的时钟300ms aTimer  new System.Timers.Timer(300);  aTimer.Elapsed  OnTimedEvent;  aTimer.AutoReset  true;  aTimer.Enabled  true; 异步写文件(VB.NET) protected void OnButton4Clicked(object sender, EventArgs e){Task r Writedata();async Task Writedata(){await Task.Run(() {VB.FileSystem.FileOpen(1, VBNETTEST.TXT, VB.OpenMode.Output, VB.OpenAccess.Write, VB.OpenShare.Shared);VB.FileSystem.WriteLine(1, Hello World! -
